Gelöst wird diese Aufgabe durch die Merkmale des Anspruchs 1 . Der erfindungsgemäße Befestiger mit den Merkmalen des Anspruchs 1 weist ein Hintergreifteil mit einem Gewinde auf, wobei das Hintergreifteil schmaler und länger als ein Schlitz einer Montageschiene breit ist, so dass das Hintergreifteil in Längsrichtung der Montageschiene ausgerichtet durch den Schlitz in die Montageschiene einbringbar und durch eine Drehung um eine Längsachse des Befestigers in der Montageschiene schräg- oder quergestellt werden kann, so dass das Hintergreifteil die Montageschiene von innen seitlich des Schlitzes hintergreift. Unabhängig von einer Montageschiene bedeutet "schmaler und länger als der Schlitz der Montageschiene breit", dass das Hintergreifteil radial zu einer Achse ihres Gewindes, die der Längsachse des Befestigers entspricht, in einer Richtung länger als quer zu dieser Richtung ist, wobei „quer" insbesondere orthogonal bedeutet. Zur Befestigung eines Anbauteils an einer Anlagefläche au ßen an der Montageschiene weist das Hintergreifteil das Gewinde auf, wobei das Gewinde ein Innengewinde eines Gewindelochs oder ein Außengewinde an einem Schaft oder dgl. des Hintergreifteils sein kann. Im Falle eines Gewindelochs kann das Hintergreifteil auch als Mutter aufgefasst werden, die länger als breit ist, im Falle
eines Schafts mit einem Au ßengewinde kann das Hintergreifteil auch als Hammerkopfschraube aufgefasst werden. This problem is solved by the features of claim 1. The fastener according to the invention with the features of claim 1 has a rear engagement part with a thread, wherein the rear grip part is narrower and longer than a slot of a mounting rail wide, so that the rear engagement part in the longitudinal direction of the mounting rail aligned through the slot in the mounting rail and introduced by a Rotation about a longitudinal axis of the fastener in the mounting rail can be obliquely or transversely placed so that the rear engagement member engages behind the mounting rail from the inside of the slot laterally. Regardless of a mounting rail, "narrower and longer than the slot of the mounting rail wide" means that the rear engagement portion is radially longer in one direction than one axis transverse to an axis of its thread corresponding to the longitudinal axis of the fastener, "transverse" in particular For fastening an attachment to a contact surface on the mounting rail, the rear engagement part has the thread, wherein the thread may be an internal thread of a threaded hole or an external thread on a shaft or the like of the rear grip part also be understood as a mother who is longer than wide, in the case a shaft with an external thread, the rear grip part can also be regarded as a hammer head screw.
Des Weiteren weist der erfindungsgemäße Befestiger einen Halter auf, der das Hintergreifteil hält und mit dem das Hintergreifteil durch den Schlitz in die Montageschiene einbringbar und in der Montageschiene durch Drehung um die Längsachse des Befestigers in die Hintergriffstellung schräg- oder querstellbar ist. Das Hintergreifteil steht hierzu mit seiner längeren Seite in - bezogen auf die Längsachse des Befestigers - radialer Richtung über den Halter über. Am Halter sind zwei Widerlager einander gegenüber angeordnet, die in gleichen Richtungen, radial zur Längsachse des Befestigers, seitlich vom Halter abstehen, wie das Hintergreifteil vom Halter übersteht. Anders ausgedrückt stehen die Widerlager in parallele radiale Richtungen bezüglich einer Achse des Gewindes des Hintergreifteils wie das Hintergreifteil vom Halter übersteht. Die Widerlager sind axial in Bezug auf das Gewinde des Hintergreifteils, also in Richtung der Längsachse des Befestigers, versetzt zum Hintergreifteil am Halter angeordnet. Die Widerlager des Halters übergreifen die Anlagefläche der Montageschiene außen seitlich des Schlitzes, wenn der Befestiger wie vorgesehen an der Montageschiene angeordnet ist und sich das Hintergreifteil in der die Montageschiene innen seitlich des Schlitzes hintergreifenden Hintergriffstellung befindet, jedoch noch kein Anbauteil über den Befestiger mit der Montageschiene verbunden ist, der Befestiger sich also in einer Vormontagestellung befindet.

On the holder, two abutments are arranged opposite to each other, which protrude laterally from the holder in the same directions, radially to the longitudinal axis of the fastener, as the rear grip part protrudes from the holder. In other words, the abutments are in parallel radial directions with respect to an axis of the thread of the rear grip part as the rear grip part protrudes from the holder. The abutments are arranged axially with respect to the thread of the rear engagement part, ie in the direction of the longitudinal axis of the fastener, offset from the rear engagement part on the holder. The abutment of the holder overlap the contact surface of the mounting rail outside the side of the slot when the fastener is arranged as provided on the mounting rail and the rear grip in the mounting rail inside the slot laterally behind the rear handle position is, but still no attachment on the fastener with the mounting rail is connected, the fastener is thus in a pre-assembly.

Wird der Halter in die Montageschiene hinein beaufschlagt, bewegen sich die Widerlager aufeinander zu und gelangen dadurch in den Schlitz der Montageschiene hinein, so dass sie nicht auf einer Außenseite der Montageschiene aufliegen. Die Beaufschlagung des Halters des erfindungsgemäßen Befestigers in die Montageschiene hinein erfolgt beispielsweise durch ein Anbauteil, das mit dem erfindungsgemäßen Befestiger an der Montageschiene befestigt und auf der Seite des Schlitzes au ßen gegen die Anlagefläche der
Montageschiene gespannt wird. Das Anbauteil drückt in diesem Fall zunächst gegen die an der Montageschiene au ßen über die Anlagefläche überstehenden Widerlager, die durch den Druck aufeinander zu und in den Schlitz der Montageschiene hinein bewegt werden, so dass die Widerlager und auch kein sonstiges Element des Halters oder Befestigers zwischen das Anbauteil und die Montageschiene greifen, so dass das Anbauteil unmittelbar außen seitlich neben dem Schlitz auf der Anlagefläche der Montageschiene anliegt. Die Beweglichkeit der Widerlager ermöglicht eine große Maß- und Formtoleranz sowohl der Widerlager des Halters als auch der Montageschiene und ihres Schlitzes. According to the invention, the abutments on the holder are movable towards each other, so that a distance of the abutments from each other can be reduced. If the holder is acted upon in the mounting rail, the abutment move towards each other and thereby enter into the slot of the mounting rail, so that they do not rest on an outer side of the mounting rail. The loading of the holder of the fastener according to the invention in the mounting rail into, for example, by an attachment which secured with the fastener according to the invention to the mounting rail and on the side of the slot au Shen against the contact surface of Mounting rail is tensioned. The attachment presses in this case, first against the on the mounting rail au Shen over the contact surface protruding abutment, which are moved by the pressure towards each other and into the slot of the mounting rail, so that the abutment and no other element of the holder or fastener between the attachment and the mounting rail engage, so that the attachment rests directly outside laterally next to the slot on the contact surface of the mounting rail. The mobility of the abutment allows a large dimensional and form tolerance of both the abutment of the holder and the mounting rail and its slot.
Die Erfindung ermöglicht eine Herstellung des Halters des Befestigers beispielsweise aus Kunststoff, ohne dass ein "Kriechen" des Kunststoffs zu besorgen ist. Mit "Kriechen" ist eine langsame plastische Verformung unter mechanischer Dauerbeanspruchung gemeint, hier insbesondere von Kunststoff, der zwischen der Montageschiene und einem Anbauteil eingespannt ist. Weil sich die Widerlager des Halters des erfindungsgemäßen Befestigers bei der Montage eines Anbauteils in den Schlitz der Montageschiene hineinbewegen und dabei die Anlagefläche der Montageschiene zur direkten Anlage des Anbauteils freigeben, erfordert die Erfindung keine spezielle Montageschiene. Vorzugsweise federn die Widerlager des Halters des erfindungsgemäßen Befestigers in einer Bewegungsrichtung der Widerlager, sie lassen sich federnd bzw. durch elastische Verformung in den Schlitz der Montageschiene hineinbewegen. So lange der Halter nicht in die Montageschiene hinein beaufschlagt wird, hält eine Federkraft die Widerlager außen in der die Montageschiene seitlich des Schlitzes übergreifenden Stellung, in der die Widerlager über die Anlagefläche der Montageschiene überstehen. The invention enables a production of the holder of the fastener, for example made of plastic, without having to get a "creep" of the plastic. By "creep" is meant a slow plastic deformation under permanent mechanical stress, here in particular of plastic, which is clamped between the mounting rail and an attachment. Because the abutment of the holder of the fastener according to the invention move into the slot of the mounting rail during assembly of an attachment and thereby release the contact surface of the mounting rail for direct contact of the attachment, the invention requires no special mounting rail. Preferably, the abutment of the holder of the fastener of the invention in a direction of movement of the abutment, they can resiliently or by elastic deformation into the slot of the mounting rail move into it. As long as the holder is not acted upon in the mounting rail, a spring force holds the abutment outside in the mounting rail laterally of the slot cross-position in which the abutment survive on the contact surface of the mounting rail.
Eine Ausgestaltung der Erfindung sieht vor, dass der Halter in einer Achsrichtung des Gewindes des Hintergreifteils bzw. in Richtung der Längsachse des Befestigers federt, so dass der Halter das Hintergreifteil federnd von innen gegen die Montageschiene beaufschlagt, wenn sich das Hintergreifteil in der Hintergriffstellung befindet. Dadurch wird die Montageschiene zwischen dem Hintergreifteil auf der Innenseite der Montageschiene und den Widerlagern auf der Au ßenseite der Montageschiene, die insbesondere an der Anlagefläche anliegen, festgeklemmt und der Befestiger gegen unbeabsichtigtes Verschieben in Längsrichtung an der Montageschiene gehalten. Der Befestiger lässt sich durch Überwinden einer Klemmkraft in Längsrichtung der Montageschiene an eine gewünschte Position verschieben. Eine endgültige Festlegung
des Befestigers an der Montageschiene erfolgt durch Festspannen eines Anbauteils an dem Befestiger mit beispielsweise einer in ein Innengewinde des Hintergreifteils eingeschraubten Schraube oder einer auf ein Au ßengewinde an einem Schaft des Hintergreifteils geschraubten Mutter. An embodiment of the invention provides that the holder springs in an axial direction of the thread of the rear grip part or in the direction of the longitudinal axis of the fastener, so that the holder acts on the rear grip part resiliently from the inside against the mounting rail when the rear grip part is in the rear grip position. As a result, the mounting rail between the rear engagement part on the inside of the mounting rail and the abutments on the Au ßenseite the mounting rail, which rest in particular on the contact surface, clamped and held the fastener against unintentional displacement in the longitudinal direction of the mounting rail. The fastener can be moved by overcoming a clamping force in the longitudinal direction of the mounting rail to a desired position. A final determination the fastener to the mounting rail is made by tightening an attachment to the fastener with, for example, a screw screwed into an internal thread of the rear grip part or a screwed on a Au ßengewinde on a shaft of the rear grip nut.
Eine Ausgestaltung der Erfindung sieht vor, dass die Widerlager von einander abgewandten Au ßenseiten von Federelementen, insbesondere Federzungen, des Halters abstehen. Die Federelemente befinden sich außerhalb einer Mantelfläche des Gewindes des Hintergreifteils, so dass beispielsweise ein Schaft einer Schraube zwischen den Federelementen durch in das Gewinde des Hintergreifteils schraubbar ist. Die Federelemente erstrecken sich von den Widerlagern in Richtung des Hintergreifteils und gehen an den Widerlagern fernen Enden einstückig in den Halter über. Diese Ausgestaltung der Erfindung ermöglicht eine einstückige Herstellung des Halters mit den Widerlagern in einem Arbeitsschritt durch Spritzgießen aus Kunststoff, wobei die Erfindung weder auf diesen Werkstoff noch auf die Herstellung durch Spritzgießen beschränkt ist. An embodiment of the invention provides that the abutment facing away from each other Au ßenseiten of spring elements, in particular spring tongues, the holder protrude. The spring elements are located outside a lateral surface of the thread of the rear grip part, so that, for example, a shaft of a screw between the spring elements can be screwed through into the thread of the rear grip part. The spring elements extend from the abutments in the direction of the rear grip part and go on the abutments far ends in one piece in the holder. This embodiment of the invention enables a one-piece production of the holder with the abutments in one step by injection molding of plastic, the invention is not limited to this material nor to the production by injection molding.
Eine Ausgestaltung der Erfindung sieht vor, dass die Widerlager Schrägflächen an einander abgewandten und dem Hintergreifteil zugewandten Seiten aufweisen. Ist der erfindungsgemäße Befestiger wie vorgesehen an einer Montageschiene angeordnet, wobei sich das Hintergreifteil in der Hintergriffstellung in der Montageschiene befindet, liegen die Schrägflächen im Bereich eines Übergangs einer die Anlagefläche bildenden Außenseite der Montageschiene in den Schlitz an der Montageschiene an und halten den Befestiger an der Montageschiene. Durch ihre Schrägstellung drückt die Montageschiene die Widerlager nach innen, wenn ein Anbauteil montiert und dabei der Halter in die Montageschiene hinein beaufschlagt wird. D.h. die Widerlager gelangen in den Schlitz der Montageschiene, wenn ein Anbauteil mit dem Befestiger an der Montageschiene befestigt und dazu von au ßen gegen die Montageschiene gespannt wird. An embodiment of the invention provides that the abutment inclined surfaces facing away from each other and the rear grip part facing sides. If the fastener according to the invention is arranged on a mounting rail as intended, with the rear grip part being in the rear grip position in the mounting rail, the inclined surfaces lie in the region of a transition of an outer surface of the mounting rail forming the contact surface into the slot on the mounting rail and hold the fastener on the mounting rail. Due to its inclination, the mounting rail pushes the abutment inwards when an attachment is mounted, while the holder is acted upon in the mounting rail into it. That the abutment get into the slot of the mounting rail when a fixture with the fastener attached to the mounting rail and this is stretched from the outside against the mounting rail.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen: The invention will be explained in more detail with reference to an embodiment shown in the drawing. Show it:
Figur 1 eine Stirnansicht eines erfindungsgemäßen Befestigers; Figure 1 is an end view of a fastener according to the invention;
Figur 2 den Befestiger aus Figur 1 in Seitenansicht; und
Figur 3 den Befestiger aus Figuren 1 und 2 in einem gegenüber Figur 2 um 90 Grad gedrehten Achsschnitt in einer Montageschiene. Der in der Zeichnung dargestellte, erfindungsgemäße Befestiger 1 weist einen Halter 2 und ein Hintergreifteil 3 auf und ist zur Verbindung zweier Montageschienen 4 oder zur Befestigung eines Anbauteils wie beispielsweise einer Rohr- oder einer Kabelschelle an der Montageschiene 4 vorgesehen. Die Montageschiene 4, die in Figur 3 gezeichnet ist, weist einen flachen Rechteckquerschnitt und einen in Längsrichtung durchgehenden Schlitz auf einer Flachseite auf, die eine Anlagefläche 16 für ein Anbauteil bildet. Dem Schlitz gegenüber weist die Montageschiene 4 abwechselnd Lang- und Rundlöcher 5 zur Befestigung der Montageschiene 4 an beispielsweise einer Decke oder einer Wand auf. Der Halter 2 besteht aus Kunststoff und das Hintergreifteil 3 aus Metall, insbesondere aus Stahl. Die Materialwahl für den Halter 2 und das Hintergreifteil 3 ist nicht zwingend für die Erfindung. Figure 2 shows the fastener of Figure 1 in side view; and Figure 3 shows the fastener of Figures 1 and 2 in a comparison with Figure 2 rotated by 90 degrees axial section in a mounting rail. The illustrated in the drawing, fastener 1 according to the invention has a holder 2 and a rear engagement part 3 and is provided for connecting two mounting rails 4 or for attaching an attachment such as a pipe or a cable clamp to the mounting rail 4. The mounting rail 4, which is drawn in Figure 3, has a flat rectangular cross-section and a longitudinally continuous slot on a flat side, which forms a contact surface 16 for an attachment. The slot opposite the mounting rail 4 alternately long and round holes 5 for mounting the mounting rail 4 on, for example, a ceiling or a wall. The holder 2 is made of plastic and the rear grip part 3 made of metal, in particular steel. The choice of material for the holder 2 and the rear grip part 3 is not mandatory for the invention.
Das Hintergreifteil 3 ist in Ansicht rechteckig und weist ein Gewindeloch 6 mit einem Innengewinde in seiner Mitte auf, das allgemein auch als Gewinde aufgefasst werden kann. Das Gewindeloch 6 erstreckt sich in Richtung der Längsachse L des Befestigers 1 . Das Hintergreifteil 3 kann auch als Rechteckmutter aufgefasst werden. Anstelle einer Mutter ist auch die Verwendung einer Hammerkopfschraube mit einem Schaft mit Außengewinde als Hintergreifteil denkbar (nicht dargestellt). Das Hintergreifteil 3 ist schmaler und länger als der Schlitz der Montageschiene 4 breit ist und das Hintergreifteil 3 ist kürzer als eine Innenbreite der Montageschiene 4. Das Hintergreifteil 3 lässt sich dadurch in Längsrichtung der Montageschiene 4 ausgerichtet durch den Schlitz in Einbringrichtung E, d.h. in einer zur Längsachse L des Befestigers 1 parallelen oder mit ihr identischen Richtung, in die Montageschiene 4 einbringen und durch Drehung in der Montageschiene 4 quer- oder schrägstellen, so dass es die Montageschiene 4 von innen beiderseits seitlich des Schlitzes hintergreift, wie es in Figur 3 zu sehen ist. The rear grip part 3 is rectangular in view and has a threaded hole 6 with an internal thread in its center, which can be generally understood as a thread. The threaded hole 6 extends in the direction of the longitudinal axis L of the fastener first The rear grip part 3 can also be understood as a rectangular nut. Instead of a nut and the use of a hammer head screw with a shaft with external thread as a rear grip part is conceivable (not shown). The rear engagement part 3 is narrower and longer than the slot of the mounting rail 4 is wide and the rear engagement part 3 is shorter than an inner width of the mounting rail 4. The rear engagement part 3 can thereby be aligned in the longitudinal direction of the mounting rail 4 through the slot in the insertion direction E, i. in a direction parallel to the longitudinal axis L of the fastener 1 or identical with her direction, bring in the mounting rail 4 and transverse by rotation in the mounting rail 4 or tilted so that it engages behind the mounting rail 4 from the inside on both sides of the slot, as shown in FIG 3 can be seen.
Der Halter 2 weist einen kurzen Schaft 7 mit zylindrischer Mantelfläche und einem länglichen Flansch 8 an einer Stirnseite des Schafts 7 auf. Mit "kurz" ist gemeint, dass der Schaft 7 nicht länger als sein Durchmesser ist. Ein Durchmesser des Schafts 7 ist nicht größer als eine Breite des Schlitzes der Montageschiene 4, so dass der Schaft 7 in den Schlitz der Montageschiene 4 einbringbar ist. Der Schaft 7 weist eine radial durchgehende Öffnung als Aufnahme des Hintergreifteils 3 mit axialem Abstand vom
Flansch 8 auf. Ein Querschnitt der die Aufnahme bildenden Öffnung ist kongruent zu einem Querschnitt des Hintergreifteils 3. Das Hintergreifteil 3 steht bezogen auf die Längsachse L des Befestigers radial auf beiden Seiten aus dem Schaft 7 vor. Das Hintergreifteil 3 ist in diesem Fall quer, hier orthogonal zu dem länglichen Flansch 8 angeordnet und steht an Längsseiten des Flanschs 8 aus dem Schaft 7 vor. Auf einer dem Flansch 8 abgewandten Seite des Hintergreifteils 3 weist der Schaft 7 zwei elastische Federfinger 9 auf, die sich in Umfangsrichtung erstrecken und die das Hintergreifteil 3 elastisch federnd in Richtung des Flanschs 8 beaufschlagen. Der Halter 2 weist ein koaxiales Durchgangsloch 15 auf, dessen Durchmesser größer als ein Außendurchmesser des Gewindes des Hintergreifteils 3 ist. The holder 2 has a short shaft 7 with a cylindrical lateral surface and an elongate flange 8 on an end face of the shaft 7. By "short" is meant that the shaft 7 is no longer than its diameter. A diameter of the shaft 7 is not greater than a width of the slot of the mounting rail 4, so that the shaft 7 in the slot of the mounting rail 4 can be introduced. The shaft 7 has a radially continuous opening as a receptacle of the rear grip part 3 at an axial distance from Flange 8 on. A cross-section of the opening forming the receptacle is congruent with a cross-section of the rear grip part 3. The rear grip part 3 projects radially from the shaft 7 on both sides with respect to the longitudinal axis L of the fastener. The rear grip part 3 is in this case transversely, here arranged orthogonal to the elongated flange 8 and protrudes on longitudinal sides of the flange 8 from the shaft 7. On a side facing away from the flange 8 of the rear engagement part 3, the shaft 7 has two elastic spring fingers 9 which extend in the circumferential direction and act on the rear grip part 3 resiliently in the direction of the flange 8. The holder 2 has a coaxial through hole 15 whose diameter is larger than an outer diameter of the thread of the rear grip part 3.
Der Flansch 8 weist zwei Laschen 10 auf, die von der Seite gesehen (Figur 2) stumpfwinklig abgewinkelt sind und in entgegengesetzten Richtungen abstehen. Die Laschen 10 dienen einer Handhabung des Befestigers 1 . The flange 8 has two tabs 10, which, viewed from the side (Figure 2) are angled obtusely and protrude in opposite directions. The tabs 10 serve to handle the fastener 1.
An den Längsseiten des Flanschs 8 weist der Halter 2 zwei einander gegenüber angeordnete Federelemente 1 1 in Form von Federzungen auf, die achsparallel zum Schaft 7 an dessen Umfang angeordnet sind. Die Federelemente 1 1 befinden sich außerhalb einer Mantelfläche des Gewindes des Hintergreifteils 3. An dem Hintergreifteil 3 zugewandten Enden gehen die Federzungen 1 1 einstückig in den Schaft 7 über. Die Federelemente 1 1 federn bezogen auf die Längsachse L in radialer Richtung, d. h. zusammen und auseinander und in Längsrichtung des Hintergreifteils 3, in der das Hintergreifteil 3 radial über den Halter 2 übersteht. Die Federelemente 1 1 enden mit freien Enden bündig mit dem Flansch 8 und weisen an oder nahe an ihren freien Enden an einander abgewandten Au ßenseiten Schrägflächen 12 auf, die dem Hintergreifteil 3 zugewandt sind. Die freien Enden der Federelemente 1 1 mit den Schrägflächen 12 können auch als Widerlager 13 des Halters 2 aufgefasst werden. Die Widerlager 13 sind in Längsrichtung des Hintergreifteils 3, also in den Richtungen, in die das Hintergreifteil 3 über den Schaft 7 übersteht, aufeinander zu und voneinander weg beweglich und federnd in diesen Richtungen. On the longitudinal sides of the flange 8, the holder 2 has two oppositely disposed spring elements 1 1 in the form of spring tongues, which are arranged axially parallel to the shaft 7 at its periphery. The spring elements 1 1 are located outside a lateral surface of the thread of the rear grip part 3. At the rear grip part 3 facing ends go the spring tongues 1 1 in one piece into the shaft 7. The spring elements 1 1 springs relative to the longitudinal axis L in the radial direction, d. H. together and apart and in the longitudinal direction of the rear grip part 3, in which the rear grip part 3 projects radially beyond the holder 2. The spring elements 1 1 terminate with free ends flush with the flange 8 and have at or close to their free ends on opposite Au outside oblique surfaces 12, which are facing the rear grip part 3. The free ends of the spring elements 1 1 with the inclined surfaces 12 can also be considered as an abutment 13 of the holder 2. The abutments 13 are in the longitudinal direction of the rear engagement part 3, ie in the directions in which the rear grip part 3 projects beyond the shaft 7, toward and away from each other movable and resilient in these directions.
Zur Befestigung an der Montageschiene 4 wird der Befestiger 1 an den Laschen 10 seines Halters 2 gegriffen und der längliche Halter 10 quer und damit das Hintergreifteil 3 längs zur Montageschiene 4 ausgerichtet. Mit dieser Ausrichtung lässt sich das Hintergreifteil 3 am Halter 2 durch den Schlitz in die Montageschiene 4 einbringen. Durch eine Drehung um 90 Grad wird das Hintergreifteil 3 in der Montageschiene 4 quer in eine
in Figur 3 gezeigte Hintergriffstellung gestellt, in der das Hintergreifteil 3 die Montageschiene 4 innen seitlich des Schlitzes hintergreift. Die Widerlager 13 liegen mit ihren Schrägflächen 12 elastisch federnd an einer Außenseite der Montageschiene 4 seitlich des Schlitzes an der Montageschiene 4 an. Die Schrägflächen 12 der Widerlager 13 liegen im Bereich eines Übergangs von der Anlagefläche 16 der Montageschiene 4 in den Schlitz an, derart, dass die dem Hintergreifteil 3 abgewandten Seiten der Widerlager 13 in Richtung der Längsachse des Befestigers 1 über die Anlagefläche 16 überstehen. Eine Federkraft der Federelemente 1 1 der Widerlager 13 und eine Federkraft der Federfinger 9 des Schafts 7, die das Hintergreifteil 3 in Richtung des Flanschs 8 beaufschlagt, klemmt den Befestiger 1 an der Montageschiene 4 fest. Eine Klemmkraft ist so hoch, dass sich auch bei einer senkrecht an einer Wand befestigten Montageschiene 4 der Befestiger 1 nicht von selbst verschiebt. Von Hand lässt sich eine Klemmkraft überwinden und der Befestiger 1 in Längsrichtung der Montageschiene 4 verschieben. Zu einer endgültigen Festlegung wird eine nicht gezeichnete Schraube durch ein Durchsteckloch in einem nicht gezeichneten Anbauteil und durch das Durchgangsloch 15 des Halters 2 in das Gewindeloch 4 des Hintergreifteils 3 geschraubt und festgezogen. Die Schraube spannt das Hintergreifteil 3 von innen gegen die Montageschiene 4 und beaufschlagt dabei den Halter 2 in die Montageschiene 4 hinein. Die Widerlager 13 werden dabei vom Anbauteil nach innen gedrückt und gelangen in den Schlitz der Montageschiene 4, so dass sie sich nicht zwischen dem Anbauteil und der Montageschiene 4 befinden. Das nicht gezeichnete Anbauteil liegt unmittelbar auf Anlagefläche 16 der Außenseite der Montageschiene 4 an.
For attachment to the mounting rail 4, the fastener 1 is gripped on the tabs 10 of its holder 2 and the elongated holder 10 transversely aligned and thus the rear engagement part 3 along the mounting rail 4. With this orientation, the rear grip part 3 can be introduced on the holder 2 through the slot in the mounting rail 4. By a rotation of 90 degrees, the rear grip part 3 in the mounting rail 4 transversely into a 3 shown behind grip position in which the rear engagement part 3, the mounting rail 4 engages behind the inside of the slot laterally. The abutment 13 are with their inclined surfaces 12 resiliently on an outer side of the mounting rail 4 side of the slot on the mounting rail 4. The inclined surfaces 12 of the abutment 13 are in the region of a transition from the contact surface 16 of the mounting rail 4 in the slot, such that the rear grip part 3 facing away from the abutment 13 in the direction of the longitudinal axis of the fastener 1 over the contact surface 16. A spring force of the spring elements 1 1 of the abutment 13 and a spring force of the spring fingers 9 of the shaft 7, which acts on the rear grip part 3 in the direction of the flange 8, clamps the fastener 1 to the mounting rail 4. A clamping force is so high that even with a mounting rail 4 fastened vertically to a wall, the fastener 1 does not shift by itself. By hand, a clamping force can overcome and move the fastener 1 in the longitudinal direction of the mounting rail 4. For a final determination, a screw not shown screwed through a through-hole in a not-shown attachment and through the through hole 15 of the holder 2 in the threaded hole 4 of the rear engagement part 3 and tightened. The screw biases the rear grip part 3 from the inside against the mounting rail 4 and acts on the holder 2 in the mounting rail 4 into it. The abutment 13 are pressed by the attachment inwards and get into the slot of the mounting rail 4 so that they are not between the attachment and the mounting rail 4. The attachment not shown lies directly on contact surface 16 of the outside of the mounting rail 4.
